One Direction's 'Temporary Fix' has ''a bit of grit to it''.
He said: ''It [the song] has got a bit of dirt to it, a bit of grit to it.
''It's basically about being in the bar, and some guy is chewing the ear off you. He's got a few drinks on him, and you can tell by her body language that she doesn't want to be there, so you come over to her, chat to her...''
He added with a cheeky smile: ''Then the chorus is basically about 'I can be your temporary fix'.
''We don't have to call it anything - just kinda... it's relatable I guess. Everyone has a grungy night out now and then.''
Meanwhile, Harry reportedly wrote their latest single 'Perfect' about his relationship with 'Shake It Off' hitmaker Taylor Swift.
A source said previously: ''Harry would never get too specific about Taylor in a song, but the lyrics are definitely going to get fans speculating.
''He doesn't want to dish the dirt but a relationship as intense as theirs has provided lots of inspiration.''
'Made in the A.M.' is set for release on November 13.
